promptfunOne prompt. No second draft.
There is a particular kind of software that everyone assumes must be hard, because the first version was. Pump.fun proved that a memecoin launchpad could be a real business — and then a hundred forks proved that copying it was a slog of audits, vesting schedules, and venture decks. We wondered what the floor actually was. So we did the unserious thing and asked Claude to build the whole thing in a single prompt.
What came back was not a toy. It was a working bonding-curve launchpad: deterministic pricing, no presale, no team bag, liquidity that locks itself the moment a token bonds. The parts that take other teams a quarter to argue about — the fee model, the fairness guarantees, the anti-snipe window — were just decisions, made once, cleanly, in the first pass.
The point isn’t that launchpads are easy. The point is that the ceremony around them was never the value. promptfun is what’s left when you delete the ceremony — the same primitive pump.fun pioneered, rebuilt without the rent-seeking, the hidden allocations, or the launch fee, and handed back to you as something you can use in the next sixty seconds.
We kept the one-shot name because it’s honest. You get one shot to launch fairly, with the curve and the rules fixed in the open before the first buy. No do-overs, no insider round, no quiet edit after the fact. The chain remembers, and so do we.
